Topographic mapping-based base map collection method, device, equipment and storage medium

Abstract

The invention provides a topographic mapping-based base map collection method, a device, equipment and a storage medium. The method comprises the steps of acquiring a remote sensing image of a presetsurveying and mapping range, and generating an aerial survey topographic map of the preset surveying and mapping range according to the remote sensing image, the aerial survey topographic map comprising a first type of ground feature elements; generating an actual measurement topographic map according to the data of the second type of ground feature elements acquired by the field collection equipment; According to the aerial survey topographic map and the actually measured topographic map, performing fusion to generate a topographic base map of a preset surveying and mapping range. The methodcomprises the following steps: dividing ground objects into different types; the aerial survey topographic map containing the first type of ground feature elements and the actual measurement topographic map containing the second type of ground feature elements are obtained in a more appropriate mode, so that the precision of the collected ground feature elements is improved, and the precision of the topographic base map, generated through ground feature element fusion, of the preset surveying and mapping range is further improved.

Description

technical field [0001] The present invention relates to the field of positioning processing, in particular to a base map acquisition method, device, equipment and storage medium based on topographic mapping. Background technique [0002] With the development of society and the improvement of information technology, group tours are inclined to self-driving tours. This change in travel methods has put forward higher demands on travel services. Tourists need to plan travel routes in advance and know how to reach their destinations; they need real-time Obtain the service facilities in the surrounding area, find out the specific location of the service facilities; in the scenic area with complex terrain, you need to know the direction and the location of your companions, etc. Tourists need to obtain location-related services more intuitively, so as to make better travel arrangements. [0003] In the existing technology, the existing electronic map is mainly used as the base map t...
